CAN_Receive_Driver

Use this Transform to filter particular messages from a CAN bus and decode the messages to deliver the individual Signals into the Harness. The Transform supports standard CAN and CAN FD.

To transmit information to the bus, see CAN Transmit Driver.

3.Select one or more nodes to Receive From.

4.Click OK. The Signals used by the selected nodes become outports on the Transform.

6.Export the inport.

The standard outports (the first 7 on the right side) are always present. When the Transform receives a CAN message, the contents of the message are parsed and transmitted from the appropriate outport. In the example below, the Arb ID  of the message is transmitted from the CAN Network 1·ArbId port.
